TRACTION-ENGINE.

*sP'EcrncA'rIoN forming part of Letters Patent No. 287,593, dat ed 1 Application filed August 13, 18 83. (no model.)

7 To all whom it may concern.- I

Be it known that I, GUSTAV A. THODE, of.

Holstein, in the county of Ida and State of Iowa, have invented a new and Improved Guide Mechanism for Traction-Engines, of which the following is a full, clear, and exact The object of my invention is to provide a new and improved mechanism for turning the front axle of a traction-engine to guide the engine in the desired direction.

The invention consists in a pivoted axle carrying the steering-wheels, and provided'with a tongue connected with an endless chain passed over two sprocket-wheels,which can be revolved by means of suitable devices by the engineer, wherebythe chain can be moved in one direction or the other, and the axle turned to one side of the engine or the other.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side viewof the front partof a traction-engine provided with my improvement, parts being broken out and others shown in section. Fig."2 is an inverted plan view of the same. Fig. 3 is a cross-sectional View. I The front axle, A, is journaled to the bottom of the fixed bolster B, on which the boiler O rests. The axle A is provided with a backwardly-projecting tongue, D, the free end of which is provided with a longitudinal aperture for receiving the stem E of a fork, F, pivoted to a block, I, clamping the edge of a grooved transverse bar, G, on which it is adapted to slide transversely to the longitudinal axis of the traction-engine. Two sprocket-wheels, H and H, are journaled on the ends which engages with a cog-wheel, M, mounted on the lower end of a downwardly-inclined October 30, 1883,

is securely fastened to the upper strand of the chain, and consequently will be moved toward oneside of the engine or the other if the shaft K is turned. The moving block I acts on the tongue D, and thus inclines the front axle, A,

opposite to that in which the sliding block I moves.

I do not abandon or dedicate to the public any patentable feature set forth herein and not hereinafter claimed, but reserve the right to claim the same either in a reissue of any patent that may be granted upon this application or in any other application for Letters Patent that I may make. I

Having thus described-my invention, I claim as new and desire to secure by Letters Patent-e 1. A guide mechanism for traction-engines, consisting of an endless chain passing over sprocket wheels connected with gearing for operating them, which chain is connected with thetongue of a pivoted axle, substantially as herein shown and described.

2. In a guide mechanism for traction engines, the combination, with a pivoted axle carrying the steering-wheels, of a tongue projecting from the said axle, a sliding block held on the free end of the tongue, an endless chain secured to the sliding block, sprocket-wheels over which the chain passes, and means'for revolving thesprocket-wheels, substantially as herein shown and described.

3. In a guide mechanism,for'traction-ea I 'gines, the combination, with a pivoted axle carrying the steering-wheels, of a tongue projecting from 'the same, a sliding block on the free end of the tongue, a grooved cross-bar on which'the block slides, an endless chain se cured to the sliding block, sprocket-wheels over jwhich the chain passes, and means for revolving the said sprocket-wheels, substantially as herein shown and described. 7

gines, the combination, with a pivoted axle to the longitudinal axis of the engine. The engine will always be guided in thedirection 4. In a guide mechanism for traction-encarrying the steering-wheels, of a tongue projecting from the said axle, a fork held in the end of the tongue, a sliding block to which the tongue is pivoted, a grooved bar 011 which the block can slide, an endless, chain secured to the block, sprocket-wheels over which the chain passes, and means for revolving the sprocket-wheels, substantially as herein shown and described.

5. I11 a guide mechanism for traction-engines, the combination, with a pivoted axle carrying the steering-wheels, of a tongue projecting from the axle, which tongue has its outer end apertured longitudinally, a fork having a stem fitting loosely in the aperture in the end of the tongue, a sliding block to which the fork is pivoted, a grooved bar on which the block slides, an endless chain fastened to the sliding block, sprocketwheels over which engaging with the cog-wheel J, and: the shaft K, on the end of which the cog-wheel J is mounted, substantially as herein shown and described.
